Project Overview

Client Requirements & Background

To support the strategic role of Qingdao Jiaodong International Airport as a regional aviation hub and accommodate projected passenger growth, the construction of its Integrated Transportation Center (GTC) and Parking Complex demanded a solution capable of delivering large spans, open spaces, high safety standards, and rapid construction. The client required a structural system that guaranteed superior performance and seismic safety while significantly shortening the build timeline and minimizing disruption to ongoing airport operations.

Key Project Challenges

Sensitivity of Operational Environment & Construction Coordination: The project's proximity to active airport operational zones necessitated strict control over noise, dust, and logistics of large component transportation to ensure unimpaired airport safety and efficiency.
Balancing Large-Space Functionality with Structural Efficiency: The GTC required expansive, column-free areas to optimize passenger and vehicle flow, placing higher demands on the span and load-bearing efficiency of the primary structure.
High-Standard Durability Requirements: As critical public infrastructure, the buildings required a long service life, low maintenance costs, and exceptional corrosion and fire resistance to meet the challenges of a coastal environment.

Solution Highlights

We delivered a fully prefabricated Steel Wall Framing System tailored for the GTC and Parking Complex, offering the following core advantages:
End-to-End Industrialized Construction: The primary steel frame and enclosure systems were precision-prefabricated and quality-controlled off-site, enabling rapid on-site "assembly." This shift from "construction" to "manufacturing" dramatically enhanced quality and speed.
High-Performance Integrated Wall-Frame System: Innovative steel frame wall construction technology integrated the load-bearing steel skeleton with insulation and cladding in the factory, creating complete wall modules installed in a single step. This achieved perfect synergy between structure, envelope, and architectural facade.
Sustainable & Green Construction: The modular approach drastically reduced on-site wet work, construction waste, and energy consumption. The inherent recyclability of steel aligns perfectly with modern green airport development principles.

This landmark project at Qingdao Jiaodong International Airport showcases the pivotal role of advanced steel wall framing technology. Our steel frame wall construction solution, through a high degree of prefabrication and integration, ensured efficient and clean construction within a complex, sensitive environment. This modern steel wall framing system not only guarantees speed and precision but also serves as the foundation for the long-term safety and functional flexibility of major public transportation buildings.

Product Technology & Specifications

The core product applied in this project is the Large-Span Steel Frame & Wall Integrated System. This system utilizes large-diameter steel pipe columns as the primary load-bearing elements, combined with custom steel beams and integrated prefabricated wall panels to form a spatially efficient and easily assembled structure. All components underwent detailed design, digital simulation, and factory pre-assembly, ensuring on-site installation accuracy to millimeter tolerances.

Technical Details & Features

Steel Pipe Column Manufacturing:

High-precision spiral welding ensures continuous, uniform seams, offering superior mechanical performance compared to longitudinally welded pipes. Pre-bending and precise sizing techniques were used for 25mm thick plates to ensure minimal roundness deviation.

Flange faces at segment joints were machined in one pass on large factory milling machines, guaranteeing flatness and perpendicularity for on-site alignment.

Integrated Wall Panel System:

All penetrations (e.g., for lighting, vents), edge sealing, and internal conduit pre-installation were completed in the factory, delivering true "functional modularity."

Panel joints feature a multi-layer seal: embedded EPDM gasket for primary air tightness, supplemented by exterior applied weather-resistant silicone sealant for water tightness.

Digitalization & Smart Application:

The entire process utilized BIM for clash detection, construction simulation, and accurate quantity take-offs.

Major components were tagged with QR codes linking to material certificates, process records, and installation data, enabling full lifecycle traceability.

On-site drone scanning and 3D reality modeling were used for progress monitoring and as-built verification against the design model.

Safety & Efficiency Assurance:

Factory prefabrication allowed over 90% of welding and painting to be completed under controlled conditions, ensuring quality far superior to field work.

On-site work primarily involved large-scale hoisting, significantly reducing extensive scaffolding work and associated safety risks.

Value Proposition Summary

Optimized Project Schedule: Primary frame erection was approximately 50% faster compared to conventional cast-in-place concrete structures, creating significant time savings for subsequent trades.

Whole-Life-Cycle Economy: Optimized initial construction costs combined with high durability and low maintenance requirements deliver superior long-term operational economics.

Superior Structural & Architectural Performance: Provides vast, unobstructed interior spaces meeting the modern functional and aesthetic demands of transportation architecture.

Environmental Stewardship: Minimized impact on the airport environment during construction and contributed substantial energy-saving and emission-reduction benefits.
